BACKGROUND INFORMATION

-   -   WO2004110988 discloses peptidyl nitrile inhibitors as         dipeptidyl-peptidase I (DPPI) inhibitors for the treatment of a         series of diseases.     -   WO2009074829 and WO2010142985 also disclose peptidyl nitrile         inhibitors as dipeptidyl-peptidase I (DPPI) inhibitors for the         treatment asthma, COPD or allergic rhinitis.

BRIEF SUMMARY OF THE INVENTION

Dipeptidyl-aminopeptidase I (DPPI or Cathepsin C; EC3.4.141), is a lysosomal cysteine protease capable of removing dipeptides from the amino terminus of protein substrates. DPPI was first discovered by Gutman and Fruton in 1948 (J. Biol. Chem 174: 851-858, 1948). The cDNA of the human enzyme has been described in 1995 (Paris et al.; FEBS Lett 369: 326-330, 1995). The DPPI protein is processed into a mature proteolytically active enzyme consisting of a heavy chain, a light chain, and a propeptide that remains associated with the active enzyme (Wolters et al.; J. Biol. Chem. 273: 15514-15520, 1998). Whereas the other cysteine Cathepsins (e.g. B, H, K, L and S) are monomers, DPPI is a 200-kD tetramer with 4 identical subunits, each composed of the 3 different polypeptide chains. DPPI is constitutively expressed in many tissues with highest levels in lung, kidney, liver and spleen (Kominami et al.; Biol. Chem. Hoppe Seyler 373: 367-373, 1992). Consistent with its role in the activation of serine proteases from hematopoetic cells, DPPI is also relatively highly expressed in neutrophils, cytotoxic lymphocytes, natural killer cells, alveolar macrophages and mast cells. Recent data from DPPI deficient mice suggest that, besides being an important enzyme in lysosomal protein degradation, DPPI also functions as the key enzyme in the activation of granule serine proteases in cytotoxic T lymphocytes and natural killer cells (granzymes A and B; Pham et al.; Proc. Nat. Acad. Sci 96: 8627-8632, 1999), mast cells (chymase and tryptase; Wolter et al.; J Biol. Chem. 276: 18551-18556, 2001), and neutrophils (Cathepsin G, elastase and proteinase 3; Adkison et al.; J Clin. Invest. 109: 363.371, 2002). Once activated, these proteases are capable of degrading various extracellular matrix components, which can lead to tissue damage and chronic inflammation.

Thus, inhibitors of Cathepsin C could potentially be useful therapeutics for the treatment of neutrophil-dominated inflammatory diseases such as chronic obstructive pulmonary disease (COPD), pulmonary emphysema, asthma, multiple sclerosis, and cystic fibrosis (Guay et al.; Curr.

Topics Med. Chem. 10: 708-716, 2010; Laine and Busch-Petersen; Expert Opin. Ther. Patents 20: 497-506, 2010). Rheumatoid arthritis is also another chronic inflammatory disease where DPPI appears to play a role. Neutrophils are recruited to the site of joint inflammation and release Cathepsin G, elastase and proteinase 3, proteases which are believed to be responsible for cartilage destruction associated with rheumatoid arthritis. Indeed, DPPI deficient mice were protected against acute arthritis induced by passive transfer of monoclonal antibodies against type II collagen (Adkison et al.; J Clin. Invest. 109: 363.371, 2002).

In light of the role DPPI plays in activating certain pro-inflammatory serine proteases, it seems desirable to prepare compounds that inhibit its activity, which thereby inhibit downstream serine protease activity. It has been surprisingly found that the bicyclic compounds of the present invention possess potent Cathepsin C activity, high selectivity against other Cathepsins, e.g.

Cathepsin K, and in general desirable pharmacokinetic properties.

As used in the specification, however, unless specified to the contrary, the following terms have the meaning indicated and the following conventions are adhered to.

In the groups, radicals, or moieties defined below, the number of carbon atoms is often specified preceding the group, for example, C₁₋₆-alkyl means an alkyl group or radical having 1 to 6 carbon atoms.

In general in single groups like HO, H₂N, S(O), S(O)₂, NC (cyano), HOOC, F₃C or the like, the skilled artisan can see the radical attachment point(s) to the molecule from the free valences of the group itself. For combined groups comprising two or more subgroups, the last named subgroup is the radical attachment point, for example, the substituent “aryl-C₁₋₄-alkyl-” means an aryl group which is bound to a C₁₋₄-alkyl-group, the latter of which is bound to the core or to the group to which the substituent is attached.

Alternatively “*” indicates within a chemical entity the binding site, i.e. the point of attachment.

In case a compound of the present invention is depicted in form of a chemical name and as a formula in case of any discrepancy the formula shall prevail. An asterisk is may be used in sub-formulas to indicate the bond which is connected to the core molecule as defined.

Many of the followings terms may be used repeatedly in the definition of a formula or group and in each case have one of the meanings given above, independently of one another.

The term “substituted” as used herein, means that any one or more hydrogens on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valence is not exceeded, and that the substitution results in a stable compound.

The expressions “prevention”, “prophylaxis”, “prophylactic treatment” or “preventive treatment” used herein should be understood synonymous and in the sense that the risk to develop a condition mentioned hereinbefore is reduced, especially in a patient having elevated risk for said conditions or a corresponding anamnesis, e.g. elevated risk of developing metabolic disorder such as diabetes or obesity or another disorder mentioned herein. Thus the expression “prevention of a disease” as used herein means the management and care of an individual at risk of developing the disease prior to the clinical onset of the disease. The purpose of prevention is to combat the development of the disease, condition or disorder, and includes the administration of the active compounds to prevent or delay the onset of the symptoms or complications and to prevent or delay the development of related diseases, conditions or disorders. Success of said preventive treatment is reflected statistically by reduced incidence of said condition within a patient population at risk for this condition in comparison to an equivalent patient population without preventive treatment.

The expression “treatment” or “therapy” means therapeutic treatment of patients having already developed one or more of said conditions in manifest, acute or chronic form, including symptomatic treatment in order to relieve symptoms of the specific indication or causal treatment in order to reverse or partially reverse the condition or to delay the progression of the indication as far as this may be possible, depending on the condition and the severity thereof. Thus the expression “treatment of a disease” as used herein means the management and care of a patient having developed the disease, condition or disorder. The purpose of treatment is to combat the disease, condition or disorder. Treatment includes the administration of the active compounds to eliminate or control the disease, condition or disorder as well as to alleviate the symptoms or complications associated with the disease, condition or disorder.

Unless specifically indicated, throughout the specification and the appended claims, a given chemical formula or name shall encompass tautomers and all stereo, optical and geometrical isomers (e.g. enantiomers, diastereomers, E/Z isomers etc. . . . ) and racemates thereof as well as mixtures in different proportions of the separate enantiomers, mixtures of diastereomers, or mixtures of any of the foregoing forms where such isomers and enantiomers exist, as well as salts, including pharmaceutically acceptable salts thereof and solvates thereof such as for instance hydrates including solvates of the free compounds or solvates of a salt of the compound.

As used herein the term “prodrug” refers to (i) an inactive form of a drug that exerts its effects after metabolic processes within the body converting it to a usable or active form, or (ii) a substance that gives rise to a pharmacologically active metabolite, although not itself active (i.e. an inactive precursor).

The terms “prodrug” or “prodrug derivative” mean a covalently-bonded derivative, carrier or precursor of the parent compound or active drug substance which undergoes at least some biotransformation prior to exhibiting its pharmacological effect(s). Such prodrugs either have metabolically cleavable or otherwise convertible groups and are rapidly transformed in vivo to yield the parent compound, for example, by hydrolysis in blood or by activation via oxidation as in case of thioether groups. Most common prodrugs include esters and amide analogs of the parent compounds. The prodrug is formulated with the objectives of improved chemical stability, improved patient acceptance and compliance, improved bioavailability, prolonged duration of action, improved organ selectivity, improved formulation (e.g., increased hydrosolubility), and/or decreased side effects (e.g., toxicity). In general, prodrugs themselves have weak or no biological activity and are stable under ordinary conditions. Prodrugs can be readily prepared from the parent compounds using methods known in the art, such as those described in A Textbook of Drug Design and Development, Krogsgaard-Larsen and H. Bundgaard (eds.), Gordon & Breach, 1991, particularly Chapter 5: “Design and Applications of Prodrugs”; Design of Prodrugs, H. Bundgaard (ed.), Elsevier, 1985; Prodrugs: Topical and Ocular Drug Delivery, K. B. Sloan (ed.), Marcel Dekker, 1998; Methods in Enzymology, K. Widder et al.

Preparation

General Synthetic Methods

The invention also provides processes for making a compound of Formula I. In all methods, unless specified otherwise, R¹, R² and n in the formulas below shall have the meaning of R¹, R² and n in Formula I of the invention described herein above.

Optimal reaction conditions and reaction times may vary depending on the particular reactants used. Unless otherwise specified, solvents, temperatures, pressures, and other reaction conditions may be readily selected by one of ordinary skill in the art. Specific procedures are provided in the Synthetic Examples section. Typically, reaction progress may be monitored by thin layer chromatography (TLC) or LC-MS, if desired, and intermediates and products may be purified by chromatography on silica gel, HPLC and/or by recrystallization. The examples which follow are illustrative and, as recognized by one skilled in the art, particular reagents or conditions could be modified as needed for individual compounds without undue experimentation. Starting materials and intermediates used, in the methods below, are either commercially available or easily prepared from commercially available materials by those skilled in the art.

A compound of Formula V, VII and IX may be made by the method outlined in Scheme 1:

As illustrated in Scheme 1, a compound of Formula II, wherein PG represents a protecting group (e.g. tert-butoxycarbonyl), may be reacted with an aqueous ammonia solution, using standard literature procedures for the formation of an amide. For example, in the presence of a base such as N-methyl-morpholine or N-ethyl-morpholine and an activating agent such as O-(7-Azabenzotriazol-1-yl)-N, N, N′, N′-tetramethyluronium hexafluorophosphate (HATU) or O-(Benzotriazol-1-yl)-N, N, N′, N′-tetramethyluroniumtetrafluoroborate (TBTU). The reaction is conveniently carried out in a suitable solvent such as N, N-dimethylformamide. Standard peptide coupling reactions known in the art (see for example M. Bodanszky, 1984, The Practice of Peptide Synthesis, Springer-Verlag) may be employed in these syntheses.

Dehydration of an amide such as in a compound of Formula III or Formula IX to the corresponding nitrile of Formula IV or VII may be carried out by use of a dehydration agent such as (methoxycarbonylsulfamoyl)triethyl ammonium hydroxide, in a suitable solvent such as dichloromethane (DCM).

Reacting an acid of Formula VI using standard literature procedures for the formation of an amide, for example in the presence of a base such as N, N-diisopropylethylamine (DIPEA) and an activating agent such as HATU or TBTU, with an amine of Formula V or VIII in a suitable solvent, provides a compound of Formula VII or IX. Standard peptide coupling reactions known in the art (see for example M. Bodanszky, 1984, The Practice of Peptide Synthesis, Springer-Verlag) may be employed in these syntheses.

The protection and deprotection of functional groups is described in ‘Protective Groups in Organic Synthesis’, T. W. Greene and P. G. M. Wuts, Wiley-Interscience. For example, for the deprotection of tert-butoxycarbonyl, an acid such as formic acid, trifluoroacetic acid, p-toluenesulfonic acid or HCl may be used in a suitable solvent such as water, DCM or dioxane. Another method to deprotect tert-butoxycarbonyl is the reaction with trimethyliodosilane or trimethylchlorosilane in combination with sodium iodide in an appropriate solvent like acetonitrile, DMF or DCM.

During the reaction sequences depicted in Scheme 1 and Scheme 2 a hydroxy group (X═OH) can be converted to a trifluoromethanesulfonyl group (X=OTf) at any level. Especially, a compound IX with X═OH is transformed to the appropriate triflate (X=OTf) by reaction with N,N-bis-(trifluoromethanesulfonyl) aniline, or trifluoromethanesulfonyl chloride or anhydride, in the presence of an organic base e.g. triethylamine, morpholine, piperidine, DIPEA in an appropriate anhydrous solvent, e.g. DCM.

As illustrated in Scheme 2, (transition) metal catalyzed reaction of a compound of Formula VII or IX wherein X is I, Br, Cl or OTf, provides a compound of Formula X or XI. For example, reaction with a boronic acid or the corresponding boronic acid ester, in a suitable solvent such as acetonitrile, in the presence of a suitable catalyst such as 1, 1-bis(di-tert-butylphosphino)ferrocene palladium dichloride and a suitable base such as K₂CO₃ provides a compound of Formula X or XI. Alternatively, reaction of a compound of Formula VII or IX, wherein X is I, Br, Cl or OTf with a tributyl(vinyl)tin reagent in the presence of a suitable catalyst such as bis-(triphenylphosphin)-palladiumchloride, in a suitable solvent such as dimethylformamide (DMF) and if desireable in the presence of an additive such as tetraethylammonium chloride provides compounds of Formula X or XI. Further, reaction of a compound of Formula VII or IX, wherein X is I or Br, may be reacted with an amine in the presence of a suitable catalyst such as Cu(I)I and a suitable base such as caesium carbonate and a suitable promotor such as L-proline provides a compound of Formula X or XI.

In an inversed fashion compounds of formula VII or IX (X: I, Br, Cl, OTf) can be converted into the corresponding boronic acid derivatives VIIa or IXa, wherein R can be H or lower alkyl independently and the residues R can form a ring. For example, VII or IX can be reacted with bis-pinacolato-diboron in the presence of a suitable catalyst such as 1, 1-bis(di-tert-butylphosphino)ferrocene palladium dichloride and a suitable base such as potassium acetate or sodium, potassium or cesium carbonate or phosphate, in a suitable solvent such as dioxan, dimethylformamide (DMF), or dichloromethane (DCM) to yield the boronic esters VIIa or IXa, respectively. These can be reacted with appropriate aromatic halides in analogy as above to yield the desired coupling products of formula X or XI.

Further, as illustrated in Scheme 2, reaction of a compound of Formula VII or IX, wherein X is N₃ with an alkyne in the presence of a suitable catalyst such as copper(II)sulfate pentahydrate and a suitable reducing agent such as L-ascorbic acid in a suitable solvent such as dimethyl sulfoxide (DMSO)/water provides a compound of Formula X or XI.

Further modifications of compounds of Formula X, XI and I by methods known in the art and illustrated in the Examples below, may be used to prepare additional compounds of the invention. Dehydration of an amide of Formula XI to the corresponding nitrile of Formula X may be carried out by use of a dehydration agent such as (methoxycarbonylsulfamoyl)triethyl ammonium hydroxide, in a suitable solvent such as DCM.

As illustrated in Scheme 3, (transition) metal catalyzed reaction of a compound of Formula IV wherein X is I, Br, Cl or OTf, provides a compound of Formula XII. For example, reaction with a boronic acid or the corresponding boronic acid ester, in a suitable solvent such as acetonitrile, in the presence of a suitable catalyst such as 1, 1-bis(di-tert-butylphosphino)ferrocene palladium dichloride and a suitable base such as K₂CO₃ provides a compound of Formula XII.

An acid of Formula VI using standard literature procedures for the formation of an amide, for example in the presence of a base such as DIPEA and an activating agent such as HATU or TBTU, can be reacted with an amine of Formula XII in a suitable solvent. Standard peptide coupling reactions known in the art (see for example M. Bodanszky, 1984, The Practice of Peptide Synthesis, Springer-Verlag) may be employed in these syntheses. Deprotection of functional groups is described in ‘Protective Groups in Organic Synthesis’, T. W. Greene and P. G. M. Wuts, Wiley-Interscience. For example, for the deprotection of tert-butoxycarbonyl, an acid such as formic acid, p-toluenesulfonic acid, trifluoroacetic acid or HCl may be used in a suitable solvent such as water, DCM or dioxane and can be performed on the crude amide coupling product to provide a compound of Formula I. Another method to deprotect tert-butoxycarbonyl is the reaction with trimethyliodosilane or trimethylchlorosilane in combination with sodium iodide in an appropriate solvent like acetonitrile, DMF or DCM.

As illustrated in Scheme 4, amino nitrile derivatives of Formula XIII can be converted to substituted amino nitriles of Formula V via alkylation to compounds of Formula XIV, followed by deprotection of the amino group. During the alkylation step a suitable base is used in an appropriate solvent, using a benzylation agent XV with an appropriate leaving group like Cl, Br, or sulfonates. Especially useful is the use of sodium hydroxide as base in water and DCM under phase transfer conditions using benzyltrimethylammonium chloride as described for example by Naidu et al, WO2011/46873. The protective group is removed under acidic conditions, e.g. aq. HCl in dioxan. The amino nitrile V is further processed as depicted in Scheme 1.

As illustrated in Scheme 5, nitro compounds of formula XV can be reduced to anilines of formula XVI by catalytic hydrogenation under conditions, where the nitrile group is still stable. Better suited are reagents like sodium dithionite, SnCl₂ or iron in a suitable solvent like water, methanol, ethanol, acetonitrile or ethyl acetate.

Reacting of 2-halo-benzoic acid, especially 2-iodo-benzoic acid using standard literature procedures for the formation of an amide, for example in the presence of a base such as N, N-diisopropylethylamine (DIPEA) and an activating agent such as HATU or TBTU, with an amine of Formula XVI in a suitable solvent, provides a compound of Formula XVII. Standard peptide coupling reactions known in the art (see for example M. Bodanszky, 1984, The Practice of Peptide Synthesis, Springer-Verlag) may be employed in these syntheses.

The benzoic amide group as in Formula XVII can be protected by an acid labile group, especially by alkoxymethyl or silylalkoxymethyl groups as mentioned for example in ‘Protective Groups in Organic Synthesis’, T. W. Greene and P. G. M. Wuts, Wiley-Interscience. Especially useful is the use of 2-trimethylsilylethoxymethylchloride as alkylating agent after having removed the amide proton by a strong base such as NaH in an inert solvent like DMF, THF or dioxan. The products are compounds of the formula XVIII.

Cyclisation of compounds like formula XVIII can be performed with the aid of a palladium catalyst like Pd(PPh₃)₄ (tetrakis(triphenylphosphine)palladium(0) and a base like potassium acetate or sodium, potassium or cesium carbonate or phosphate, especially sodium carbonate in a suitable solvent, e.g. DMF, preferrably under elevated temperature. This results in the formation of compound of the formula XIXa and XIXb, which can be separated or processed further as a mixture.

Compounds like XIXa or XIXb or a mixture thereof can be deprotected in acidic medium. Deprotection of functional groups is described in ‘Protective Groups in Organic Synthesis’, T. W. Greene and P. G. M. Wuts, Wiley-Interscience. For example, an acid such as formic acid, p-toluenesulfonic acid, trifluoroacetic acid or HCl may be used in a suitable solvent such as water, DCM or dioxane and can be performed on the crude amide coupling product to provide a compound of Formula XXa and XXb. Another method to deprotect first the tert-butoxycarbonyl is the reaction with trimethyliodosilane or trimethylchlorosilane in combination with sodium iodide in an appropriate solvent like acetonitrile, DMF or DCM. After that the trimethylsilylmethoxymethyl group can be removed in acidic medium as mentioned above, especially with formic acid again leading to compounds of the formula XXa and XXb.

Pharmacological Data

Other features and advantages of the present invention will become apparent from the following more detailed examples which illustrate, by way of example, the principles of the invention.

Inhibition of Human DPPI (Cathepsin C)

Materials: Microtiterplates (Optiplate-384 F) were purchased from PerkinElmer (Prod. No. 6007270). The substrate Gly-Arg-AMC was from Biotrend (Prod.-No. 808756 Custom peptide). Bovine serum albumin (BSA; Prod. No. A3059) and Dithiothreitol (DTT; Prod. No D0632) were from Sigma. TagZyme buffer was from Riedel-de-Haen (Prod.-No. 04269), NaCl was from Merck (Prod.-No. 1.06404.1000) and morpholinoethane sulfonic acid (MES), was from Serva (Prod.-No. 29834). The DPP1 inhibitor Gly-Phe-DMK was purchased from MP Biomedicals (Prod.-No. 03DK00625). The recombinant human DPPI was purchased from Prozymex. All other materials were of highest grade commercially available.

The following buffers were used: MES buffer: 25 mM MES, 50 mM NaCl, 5 mM DTT, adjusted to pH 6.0, containing 0.1% BSA; TAGZyme Buffer: 20 mM NaH₂PO₄, 150 mM NaCl adjusted to pH 6.0 with HCl

Assay Conditions:

The recombinant human DPPI was diluted in TAGZyme buffer to 1 U/ml (38.1 μg/ml, respectively), and then activated by mixing in a 1:2 ratio with a Cysteamine aqueous solution (2 mM) and incubating for 5 min at room temperature.

Five uL test compound (final concentration 0.1 nM to 100 μM) in aqua bidest (containing 4% DMSO, final DMSO concentration 1%) were mixed with 10 μL of DPPI in MES buffer (final concentration 0.0125 ng/μL) and incubated for 10 min. Then, 5 μL of substrate in MES buffer (final concentration 50 μM) were added. The microtiter plates were then incubated at room temperature for 30 min. Then, the reaction was stopped by adding 10 μL of Gly-Phe-DMK in MES-buffer (final concentration 1 μM). The fluorescence in the wells was determined using a Molecular Devices SpectraMax M5 Fluorescence Reader (Ex 360 nm, Em 460 nm) or an Envision Fluorescence Reader (Ex 355 nm, Em 460 nm).

Each assay microtiter plate contained wells with vehicle controls (1% DMSO in bidest+0.075% BSA) as reference for non-inhibited enzyme activity (100% Ctl; high values) and wells with inhibitor (Gly-Phe-DMK, in bidest+1% DMSO+0.075% BSA, final concentration 1M) as controls for background fluorescence (0% Ctl; low values).

The analysis of the data was performed by calculating the percentage of fluorescence in the presence of test compound in comparison to the fluorescence of the vehicle control after to subtracting the background fluorescence using the following formula:

Cell density: 0.2-1 Mio. Cells/ml.

Medium: RPMI1640 GlutaMAX (No. 61870) with 10% FCS from Gibco

Cell Seeding and Treatment:

Compounds in 100% DMSO were diluted in Medium (-FCS) with 10% DMSO and further diluted according to the experiment planned.

20 μl of the compound solution was tranferred in the respective wells of the 24 well plate and diluted with 2 ml cell suspension/well containing 1′105 cells/ml (final concentration of DMSO=0.1%). Compound dilution factor=100

Compounds (up to 7 concentrations) were tested in triplicates with 3 wells for the DMSO 0.1% control, incubatet for 48 hours without medium change at 37° C., 5% CO2 and 95% relative humidity.

Cell Harvesting and Cell Lysate:

Transfer the cell suspension in 2.2 ml Eppendorf cups. Separate cells from medium by centrifugation (400×g; 5 min; RT); discard the supernatant. Resuspend in 1 ml PBS; centrifugation (400×g; 5 min; RT); wash cells twice with PBS. Add 100 μl Serin lysis buffer (ice cold) to the cell pellet; resuspend the pellet and store on ice for 15 minutes.

The increase in fluorescence (Ex360 nm/Em 460 nm) is determined over 30 minutes with a Molecular Device Spectramax M5 Fluorescence Reader. Kinetic Reduction (Vmax units/sec); 4 vmax points. The amount of neutrophil elastase (ng/ml) is calculated using the standard curve and the Spectramax software. The result is interpolated to ng/mg lysate protein using excel formula functions. Percent inhibition in the compound-treated lysate samples is calculated relative to the DMSO-treated control-sample (100−(compound-sample*100)/control-sample)

A test compound will give values between 0% and 100% inhibition of neutrophil elastase. IC50 is calculated using Graphpad Prism; nonlinear fitting (log(inhibitor) vs. response—Variable slope). The IC50 value is interpolated as the concentration of test compound which leads to a neutrophil elastase activity reduction of 50% (relative to the DMSO-treated control).

Inhibition of Human Cathepsin K

Materials: Microtiterplates (Optiplate-384 F were purchased from PerkinElmer (Prod. No. 6007270). The substrate Z-Gly-Pro-Arg-AMC was from Biomol (Prod.-No. P-142). L-Cysteine (Prod. No. 168149) was from Sigma. Sodium actetate was from Merck (Prod.-No. 6268.0250), EDTA was from Fluka (Prod.-No. 03680). The inhibitor E-64 was purchased from Sigma (Prod.-No. E3132). The recombinant human Cathepsin K proenzyme was purchased from Biomol (Prod. No. SE-367). All other materials were of highest grade commercially available.

The following buffers were used: Activation buffer: 32.5 mM sodium acetate, adjusted to pH 3.5 with HCl; Assay buffer: 150 mM sodium acetate, 4 mM EDTA, 20 mM L-Cysteine, adjusted to pH 5.5 with HCl,

Assay Conditions:

To activate the proenzyme, 5 μl procathepsin K were mixed with 1 ul activation buffer, and incubated at room temperature for 30 min.

5 μL test compound (final concentration 0.1 nM to 100 μM) in aqua bidest (containing 4% DMSO, final DMSO concentration 1%) were mixed with 10 uL of Cathepsin K in assay buffer (final concentration 2 ng/μL) and incubated for 10 min. Then 5 μL of substrate in assay buffer (final concentration 12.5 μM) were added. The plates were then incubated at room temperature for 60 min. Then, the reaction was stopped by adding 10 μL of E64 in assay buffer (final concentration 1 μM). The fluorescence in the wells was determined using a Molecular Devices SpectraMax M5 Fluorescence Reader (Ex 360 nm, Em 460 nm).

Each assay microtiter plate contains wells with vehicle controls (1% DMSO in bidest) as reference for non-inhibited enzyme activity (100% Ctl; high values) and wells with inhibitor (E64 in bidest+1% DMSO, final concentration 1 μM) as controls for background fluorescence (0% Ctl; low values). The analysis of the data was performed by calculating the percentage of fluorescence in the presence of test compound in comparison to the fluorescence of the vehicle control after subtracting the background fluorescence:

Determination of Metabolic Stability with Human Liver Microsomes

The metabolic degradation of the test compound is assayed at 37° C. with pooled human liver microsomes. The final incubation volume of 100 μl per time point contains TRIS buffer pH 7.6 (0.1 M), magnesium chloride (5 mM), microsomal protein (1 mg/ml) and the test compound at a final concentration of 1 μM. Following a short preincubation period at 37° C., the reactions are initiated by addition of beta-nicotinamide adenine dinucleotide phosphate, reduced form (NADPH, 1 mM) and terminated by transfering an aliquot into acetonitrile after different time points. Additionally, the NADPH-independent degradation is monitored in incubations without NADPH, terminated at the last time point. The [%] remaining test compound after NADPH independent incubation is reflected by the parameter c(control) (metabolic stability). The quenched incubations are pelleted by centrifugation (10′000 g, 5 min). An aliquot of the supernatant is assayed by LC-MS/MS for the amount of parent compound.

The half-life (t1/2 INVITRO) is determined by the slope of the semilogarithmic plot of the concentration-time profile. The intrinsic clearance (CL_INTRINSIC) is calculated by considering the amount of protein in the incubation:

CL_INTRINSIC [μl/min/mg protein]=(ln 2/(half-life [min]*protein content [mg/ml]))*1′000.

The half-life (t1/2 INVITRO) values of selected compounds in the metabolic stability assay described above are listed in the following table
